Notes:	Update: On 10 February 2021, change made by Harpsicorder, Abuse Filter set from disallow to warn/tag. Reason is not all external links may be made in harmful intent. Added customized warning --Justarandomamerican apply to IPs, too Changed warning message & title --X Major reconfiguring of the filter has been done (along with thorough testing of the new conditions by using the examine feature). I did the following changes: 1) I changed the current page_namespace condition to "equals_to_any(page_namespace, 2, 3)", and have moved it to the very top. 2) Below that, I changed "!"sysop" in user_groups" to "!contains_any(user_groups, "autopatrol", "sysop", "bot")", and have added the autopatrolled and bot user groups. 3) Below the latter conditions, I have put the remaining three conditions inside a (), and have put both of the added_links in the same line (line 6). With the new conditions, the reconfigured filter will still function as the previous change, but it's reconfigured to something advanced, at the very least. — 64andtim Changed warning message to "MediaWiki:Abusefilter-warning-41". — 64andtim Remove user page and namespace condition -Justa Removed the parenthesis condition, placed user_editcount on the first line and placed the exempt user groups condition at the last line. – Codename Norte (3/8/24) Disable as it is effecting users adding confirmation links. -X Enable, exempting RfP. -Justa Disable, still not working. -X Re-enable again, page_prefixedtitle != 'Test_Wiki:Request_for_permissions' on line 4 was the issue; I switched it to page_id != 702 and checked if it caught anything other that TW:RfP. It finally works again! -- Codename Noreste, June 26 2024 No reason for filter 41 to remain private; I do not believe this is targeted to spammers who attempt various ways to bypass this filter, and automated spambots aren't going to try and avoid this as well. It could also allow non-admins to review this filter's log to check for spam or other kinds of false positives. But fellow administrators who help with abuse filters, you may revert this if you disagree. -- Codename Noreste, July 5 2024 Excluding user space. -- Codename Noreste, August 20 2024 Yet another attempt for this filter to only target human users who post links, and not spambots. The latter can be targeted by filter 5. -- Codename Noreste (August 21, 2024) I optimized the filter by placing added_lines first checking for https, then added added_links after that (since it tends to be expensive, and at the last I used_contains_any for specific website exclusions. The user group check was placed at the very bottom of the filter to exclude users who are manually assigned specific user groups. --Codename Noreste 01:11 3 Jan 2025 Whitelisted some more legitimate links (including Miraheze and Public Test Wiki), and I don't think we should also draw attention as well to edits containing links, IMO. --Codename Noreste 23:04 11 Jan 2025 Updating again. --Codename Noreste 18:55 21 Mar 2025 I forgot to add the notes here, but I updated and renamed it slightly, tagging only for now with a new tag, and only apply to new user accounts. --Codename Noreste 00:24 31 Mar 2025 Updating yet again, and set to warn/tag again in an effort to slow down the spambots. --Codename Noreste 16:31 31 Mar 2025 Bringing back contains_any (easier to maintain), reordering, and whitelisting Wikidata. --Codename Noreste 01:00 3 May 2025
